Wherein, infusion process is by time complete, and the medicinal liquid had in described kettle body reduces gradually, and the medicinal liquid face that floating body 201 floats on described kettle body moves down gradually with the medicinal liquid face in described kettle body; When floating body 201 move to plug 205 described liquid outlet is closed time, carry out automatically cutting off realizes transfusion closedown automatically to described tube for transfusion.
In the present embodiment, after described host computer 300 sends alarm a period of time, automatic closure member 200 cuts off automatically to described tube for transfusion, realizes transfusion and automatically closes.Further, host computer 300 sends the interval that alarm is carried out to automatic closure member 200 described tube for transfusion automatically cutting off, for the medicinal liquid in described kettle body is gradually reduced to the time that plug 205 closes described liquid outlet.
In the present embodiment, the alarm module 304 of alarm is carried out when the signal conditioning circuit 302 that described host computer 300 comprises single-chip microcomputer 301, nurse one's health fuction monitoring device for infusion 100 detection signals and infusion-completed, described alarm module 304 is controlled by single-chip microcomputer 301, described fuction monitoring device for infusion 100 connects with signal conditioning circuit 302, and described signal conditioning circuit 302 and alarm module 304 all connect with single-chip microcomputer 301; Wherein, when fuction monitoring device for infusion 100 is acoustic detection device 120, described host computer 300 also comprises the timing circuit, the drop that connect with single-chip microcomputer 301 respectively and instills state indicator module 305 and display module 303;
In step one, when fuction monitoring device for infusion 100 for acoustic detection device 120 and described testing result for there being drop to instill described kettle body time, drop instillation state indicator module 305 indicates a drop instillation; Host computer 300 was determined current transfusion speed and amount of infusion respectively according to the time of described testing result, described timing circuit record and the droplet size that pre-sets, and carried out simultaneous display by display module 303 to determined transfusion speed and amount of infusion.
Wherein, when current transfusion speed is determined, because acoustic detection device 120 can detect each drop instillation state, thus according to the testing result of acoustic detection device 120, and the interval of adjacent twice drop instillation kettle body in conjunction with described timing circuit record, just can obtain current transfusion speed.When determining current amount of infusion, according to the testing result of acoustic detection device 120, the total degree of current drop instillation kettle body is added up, and combines the droplet size pre-set, just can obtain current amount of infusion.
In actual applications, described host computer 300 comprises the communication module of carrying out radio communication with mobile terminal, and described communication module, when described fuction monitoring device for infusion 100 detects that transfusion is near completion, sends transfusion Stop message to described mobile terminal.
In actual applications, described host computer 300 is connected by cordless communication network with fuction monitoring device for infusion 100, and described cordless communication network comprises WLAN and GRPS network.
In actual applications, described floating body 201 comprises air bag.
In actual use procedure, whether whether fuction monitoring device for infusion 100 break down for monitoring present infusion process or infused.Specifically, when fuction monitoring device for infusion 100 is infrared detection device 110, its testing process is: when carrying out when infusing, make the height of light hole 112 higher because floating body 301 swims on medicinal liquid face, this can block after tabula rasa 111 infrared signal that infrared transmitter 113 sends to infrared remote receiver 114, and namely infrared transmitter 113 is to infrared remote receiver 114 not conducting; When transfusion completes, owing to there is no liquid in infusion bottle, described floating body 201 sinks to making the height reduction of light hole 112, and then make infrared transmitter 113 send infrared signal by light hole 112 to infrared remote receiver 114, infrared transmitter 113 and infrared remote receiver 114 conducting, the present infusion information monitored is sent to described host computer 300 by fuction monitoring device for infusion 100, starts and reports to the police.When fuction monitoring device for infusion 100 is acoustic detection device 120, its testing process is: when carrying out when infusing, drop can drop in be responded on drum 121 and induction drum 121 is shaken, and the monitoring probe 122 be connected with induction drum 121 is caught sound wave and changed and send signal to described host computer 300; When not having fluid drips on induction drum 121, monitoring probe 122 does not capture sound wave change, and now monitoring probe 122 notifies host computer 300 to start warning.Further, described monitoring probe 122 often monitors a drop and instills described kettle body, all indicates a drop instillation by drop instillation state indicator module 305.
In actual applications, automatic closure member 200 is meeting automatic stopping infusion when transfusion completes, specifically, when carrying out when infusing, because floating body 201 floats on medicinal liquid face; And when transfusion completes, owing to not having liquid in infusion bottle, described floating body 201 sinks to making the complete shutoff of plug 205 to fill the liquid outlet of infusion monitoring kettle 500, thus stopping infusion.
Described on end, when transfusion is near completion, host computer 300 can automatically start warning reminding medical personnel and process in time, if medical personnel do not process in time, automatic closure member 200 also can self-closed liquid-transport pipe-line.
In actual application, the digital speech that medical personnel utilize host computer 300 to show and sound and light alarm, understand the transfusion condition of each patient in time, avoids because transfusion causes unnecessary malpractice and dispute.In addition, intelligent monitoring transfusion device of the present invention can also wired alarming systems connection original in hospital, improves monitoring alarm quality.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solution of the present invention.
